IMPROVEMENT lN TOOL-HOLDERS FOR LATHES.

Specification forming part of Letters Patent No.145,684, dated D(!L1L( r16, 1873; application iiled DJCCIIlbEI 1, 1873.

To all whom it may concern:

Be it known that I, LEWIS REDER, of Wilmington, in the county of NewCastle and State of Delaware, have invented a new and ImprovedTool-Holder; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had totheaccompanying drawing forming a part of this specification, in whichFigure 1 is a central vertical section. Fig. 2 is a perspective view ofthe washer. Fig. 3 is a perspective View of the shoe.

The invention relates to the tool-holder of a slide-lathe; and consistsin a novel mode of rendering the tool adjustable in height and pitch, ashereinafter described, and pointed out in the claim.

A represents a tool-post, slotted to receive therethrough the tool B,and provided with the usual clamp setscrew O, that bears on the uppersurface of tool. D is a subjacent washer, which has the usual inclines(Z d to hold. the tool in position; but instead of making these reversedinclines of the same height, I place the one, d, higher than the other,d, and employ a shoe, E, which has its reversely-inclined ends 0 0 ,madecorrespondingly to those of the washer.

The operation is as follows: By placing the shoe E with its thick end 0upon the incline d of the washer, the tool will always be held in ahorizontal position, no matter how much it may be raised by turning thewasher, or adjusted laterally by turning the tool on the washer. On theother hand, by placing under the heel of tool the thick end 0 of shoe onthe thick end d of washer, the point will be de pressed; or, by placingthe small end 0 of shoe on the incline d of washer, the front of toolwill be thrown up.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with tool holder A, of washer D and shoe E, the twohaving corresponding inclines d d and e c, as and for the purposedescribed.

LEWIs REDER.
